Build LeetCode
NOT REALLYreplaces $35/mosaves $420/yrback to the verdict
Before step 1
you will need
- Docker installed and a willingness to trust your own container flags with untrusted code
- Your own problem statements and test cases, written by hand or from openly licensed sets
- Python 3.11 and Node for the app itself
- Time budget for the boring part: authoring adversarial test cases, not the UI
Delivery order
Scaffold the smallest runnable application and document its commands.
done whenThe project starts from a documented command in a clean checkout.
Implement the primary data model and core workflow.
done whenThe main object can be created, read and changed end to end.
Add validation, safe failure states, and persistence.
done whenBad input is refused with a readable message and nothing is left corrupted.
Cover the critical path with automated tests.
done whenThe highest-risk behavior fails the suite when it breaks.
Exercise a clean install from the README and fix every missing step.
done whenA fresh clone reaches the first successful workflow using only the README.
That is the whole plan for LeetCode. What it deliberately does not cover is below · check the gaps before you call it a replacement.
- The problem bank itself, thousands of problems with hidden tests tuned to catch the specific ways people get it wrong
- Company tags and frequency data, which is the main reason people pay for Premium
- Editorials and the discussion threads where the actual learning happens
- Contests, ratings, and the mild public humiliation that makes you keep showing up
- Any signal that you are practicing the same questions your interviewer will ask
